AIM: To elucidate a clinical difference between patients with Kawasaki disease documented with Yersinia pseudotuberculosis infection and patients with Kawasaki disease without Yersinia pseudotuberculosis infection. PATIENTS AND METHODS: From January 1985 to July 2004, 452 patients were diagnosed with Kawasaki disease. Forty-two patients had elevated antibody titres of Yersinia pseudotuberculosis and/or positive stool culture (Yersinia-positive group). Three hundred and thirty patients had no elevated antibody titres (Yersinia-negative group). We compared the clinical characteristics retrospectively. RESULTS: The age of onset in the Yersinia-positive group (3.05+/-2.20 y) was significantly higher than that in the Yersinia-negative group (2.31+/-2.05 y) (p=0.03). The age-adjusted statistical analysis demonstrated that the incidence of coronary artery lesions (dilatations plus aneurysms) in the Yersinia-positive group (22/42, 52.4%) was significantly higher than in the Yersinia-negative group (105/330, 31.8%) (p=0.001), and the incidence of additional administration of immunoglobulin in the Yersinia-positive group (13/36, 36.1%) was significantly higher than in the Yersinia-negative group (41/256, 16.0%) (p=0.004). CONCLUSION: Our data suggest that Yersinia pseudotuberculosis infection might play a role in the developing mechanism of poor response to therapy and the tendency to develop coronary artery lesions in Kawasaki disease patients.
